PULSE.pptx. UNDERSTANDING PULSE,PHYSIOLOGY,CHARACTERSTICS, FACTORS AFFECTING, AND SITES OF PULSE

A pulse is a rhythmic expansion & contraction of an artery as the heart pushes blood through the body or Pulse is an alternate expansion(rise) and recoil(fall) of an artery as the wave of blood is forced through it during the contraction of the left ventricle.
there are four characterstics of pulse
1.Rate
2.Rhythm
3.Volume
4.Tension
Normal pulse rate is-
Adults = 60-100beats/min
Children = 80-100beats/min
Infants = 100-140 beats/min
Newborns = 120-160 beats/min

2. PULSE A pulse is a rhythmic expansion & contraction of an artery as the heart pushes blood through the body Pulse is an alternate expansion(rise) and recoil(fall) of an artery as the wave of blood is forced through it during the contraction of the left ventricle

3. Heart beat creates pulse Sends blood to the arteries Delivering oxygen & nutrients to organs & tissues

4. PHYSIOLOGY OF PULSE The pulse originates from the left ventricle of the heart, during systole blood is ejected into the aorta. This creates a pressure wave that travels along the arterial walls The pressure wave moves faster than the actual blood flow During diastole, the ventricles relax & arteries recoil helping maintaining continuous blood flow The pulse can be felt where arteries lie close to the surface & over a firm structure

5. REGULATION OF PULSE Heart rate or pulse is controlled or regulated by two branches of the autonomic nervous system, that is the sympathetic & para -sympathetic nervous system through the SA node. The sympathetic stimulation increases the heart rate & the para -sympathetic stimulation decrease the heart rate.

6. CHARACTERSTICS Rate Rhythm Volume Tension

7. 1.RATE It’s the number of pulse beats in a minute Normal pulse rate is- Adults = 60-100beats/min Children = 80-100beats/min Infants = 100-140 beats/min Newborns = 120-160 beats/min

8. 2.RHYTHM It refers to the regularity of the beats. Normally the heart beats are spaced at equal intervals & they are said to be regular, when the interval varies between the beats it is said to be irregular & called dysrhythmia .

9. 3.VOLUME It refers to the fullness of the artery it reflects the strength of the left ventricular contraction. It is the force of the blood felt at each beat. It depends upon the amount of blood in the arteries. If the arteries contain a normal volume of blood the pulse is called full or large in volume. If the volume of the blood is decreased the pulse will be weak.

10. 4.TENSION It is the degree of compressibility of an artery. This is determined mainly by mean arterial blood pressure; corresponds to diastolic blood pressure. It is said to be high tension when the artery is difficult to compress & low tension when it is easy to compress.

11. FACTORS AFFECTING PULSE RATE AGE Gender Exercise Anxiety or emotion Position Pain Metabolism Increased body temperature Disease condition( eg : loss of blood, injury, shock etc.) Medication( eg : stimulant drugs like; atropine)

12. SITES OF PULSE TEMPORAL : Temporal Artery over the temporal bone CAROTIDE : Carotide artery at the sides o f the neck near the windpipe & just below the jaw. APICAL : Fifth intercostal space at the left mid- clavicular line( just below the left nipple) BRACHIAL : Medial side of the cubital fossa , medial to the biceps tendon.

13. 5 . RADIAL : The radial artery infront of the wrist below base of the thumb. 6 . FEMORA L: in the inner thigh along a crease midwat between the pubic symphysis & the anterior superior iliac spine. 7. POPLITEAL : Behind the knee, known as the popliteal fossa , which is the space between the muscles of the thigh and lower leg. 8. POSTERIOR TIBIAL : I nner side of the ankle, between the back of the medial malleolus (the prominent bony bump) and the Achilles tendon 9. DORSALIS PEDIS : dorsal surface of the foot, distal to the dorsal most prominence of the navicular bone.
